At the moment any bet which is more than 50USD will take 1 confirmation, then 2 confirmations for 200USD+ and an additional confirmation for every 300 from there, up to a maximum of 4 confirmations.
Maybe it would make more sense to allow players to keep a balance "on site" so they can play in real time. If I was playing with large amounts of money I'd for sure want to know which spin my bet was riding on before the spin happened.
I think we will have the option for players to deposit coins into their wallet with the needed info stored as a cookie on the players PC and close and send back the coins of inactive "accounts", we will always have our games work as "minigames" though, at the current moment we are looking to perfect this system first and look if there is room to expand.
We will also add some more info such as the dealers name and signals such as LAST BETS and NO MORE BETS which we receive server side. We will have to introduce outside players which are not familiar with the bitcoin economy to bitcoin in order to have everything working.
